In the oral cavity, transmigration is defined as a tooth that crosses the mid-line by more than half its length. Following extensive literature review, it was found that, although well documented with respect to mandibular canines, there were only two publications detailing maxillary cuspid transmigration. This report presents a case of transmigration where the left maxillary canine gradually crossed the mid-line and migrated to the right side in a patient with hemifacial microsomia and cleft palate. The Mupparapu classification of the migratory pattern of the mandibular canines is discussed. Various clinical considerations, as well as guidelines for general practitioners to diagnose and manage such a condition, are also discussed.
在口腔中，牙齿移位是指一颗牙齿越过中线的长度超过其自身长度的一半。经过广泛的文献综述发现，虽然下颌尖牙的牙齿移位已有充分记录，但仅有两篇文献详细描述了上颌尖牙的移位情况。本报告介绍了一例牙齿移位病例，一名患有半侧颜面短小畸形和腭裂的患者，其左上颌尖牙逐渐越过中线并向右侧移位。文中讨论了下颌尖牙移位模式的穆帕拉普分类法。还讨论了各种临床注意事项以及全科医生诊断和处理此类病症的指南。
